We went this week to ride the Zipline at to Rio. The actually zipline is a chair you sit on. That first initial take off from the ramp is exciting. Your feet are dangling and there is no way you aren't looking forward across the chasm to the next building or looking down. They then real you up backwards back to where you started. We've done other ziplines so it was fun but not terribly novel. We got the Groupon so it was a great price at $44 for my wife and I to ride. If I'd do it again... I'd go at night. You get a great view of the strip from there and it would look even better at night all lit up.
